We are here with something that we are really proud of. Let me introduce you to Voiden: https://voiden.md : A free, offline, git-native API workplace. Everything is in markdown and sits together: your API definition, docs, tests etc. Most devs we have talked to have also spent years wrestling with API design, if you are a dev, you know it's a real pain. ❌ Fixing API specs that didn’t match the code. ❌ Docs in a random tool, tests were separate, and governance was a mess. ❌ Team API design sucks. ❌ Cloud-sync feels sketchy. ❌ Bloated tools slowing down on quick tests. ❌ Specs and docs in different places break the flow. ❓ And WTH is real-time collaboration? Make a branch. Well, long story short, we got tired of all this. 🚀 Voiden is NOT another Postman clone. It’s like code: markdown specs, reusable blocks, Git-versioned, offline. And yes, it looks different than your usual API tool : we did this on purpose. ✅ Docs tie to your specs with live requests - a single source of truth. ✅ Git tracks changes; branch, diff, review - no login or cloud nonsense. Commit it (yes, the terminal is in the app), run git diff, and your team sees what changed. No login. No lock-in. No telemetry. If you are a builder, a dev or you are working with a team building awesome things, it's worth trying. ⬇️ Download and try the tool here: https://voiden.md. (linux version coming soon as well, we promise) 💬 Join the discussions and help us shape the future of voided here: https://github.com/VoidenHQ/feedback/ So you tell me, what’s your biggest API design pain?
